Answer:

The solution is (4, 1).

Step-by-step explanation:

Given system of equations,

4x + 2y = 18  ------(1)

x − y = 3 -------(2)

Equation (1) + 2 × equation (2),

We get,

4x + 2x = 18 + 6

6x = 24

[tex]\implies x =\frac{24}{6}=4[/tex]

From equation (2),

4 - y = 3

⇒ 4 = 3 + y

⇒ 4 - 3 = y

⇒ 1 = y,

Hence, the solution of the system of equations is (4, 1).
